In this article, I will cover one of the essential topics of fluid mechanics as the title shows three crucial topics—the first concerns the conservation of mass and how it plays a critical role in our daily life. The next one involves the conservation of kinetic and potential energy and is all about the flow energy of a fluid stream. The Bernoulli equation is all about considering the energies, handling them of fluid, and neglecting the viscous forces. The last topic is energy equations, which is about the conservation of energy principle. As we know that while dealing with energy in fluid mechanics, the mechanical energy can be separated from the thermal energy and end, considering it an energy loss.
So without wasting time, let us start the article with the mass.

Believing in the essence of timers in ladder logic programming, we come today with a new tutorial in which we are going to show you all about timers, the types of timers, what’s inside timers’ block of parameters, variables, and bits. In addition, techniques for using timers will be explored, and for sure, we are going to practice what we learn using the simulator. So let’s get started with our tutorial.
Timers in ladder logic programming
Guys, this is not the first time we’ve talked about timers. However, this time we are going to look into timers deeply and use the glasses of practical approach. So figure 1 shows the most important types of timers in ladder logic from left to right: the on-delay, off-delay, and retentive timers. There are differences in functionality. However, they all ...
3D Printer is an electronic machine that uses digital data to generate physical 3D models through successive layer printing. A 3D printer can make an object's physical model either scanned by a 3D scanner or designed using a CAD program. 3D Printing is an additive manufacturing technique where successive material layers create a three-dimensional object (Rapid Prototyping). The 3D printing concept is fascinating. Who is not excited about 3D printing? The use of inkjet technology in creating 3D models is a revolutionary method that costs less and saves time by eliminating the designing need for separate model parts. One can use a 3D printer to make a complete model in just a single process.
Several industries use 3D Printers in printing various out ...
Flow visualization widely uses Computational Fluid Dynamics (CFD) and physical experiments. So following are the types of patterns that can be visualized computationally and experimentally. So without wasting any time, let us start.
Streamlines and Streamtubes
There are two patterns. I will first explain the streamlines. So the definition of streamlines is as follows:
A streamline is a curve that is tangent everywhere to the instantaneous local velocity vector.
You might not understand the definition by reading it, so just for your ease, let me explain to you in few key points:
A streamline defines fluid’s motion throughout the flow field.
A streamline acts as an indicator of the instantaneous direction of motion of the fluid. To explain this situation, let me exemplify it with an ex ...
3D printing is one of the most promising technologies in recent breakthroughs. One of the most inherent benefits of 3D printing is additive innovation; it opens up an entirely new way of creating products and provides numerous benefits over traditional fabrication techniques.
Nowadays, more businesses across many industrial sectors adopt 3D printing as a viable alternative to subtractive manufacturing (acquiring machined parts online) and injection molding. We'll look at the benefits of 3D printing and how you can use this production method to benefit your company. Is it worthwhile to use 3D printing for your project?
Affordability
One of the best aspects of 3d printing is the reduced labor costs. Operating costs heavily influence the quantity of ...
Milling is a machining process that can create detailed or complex shapes from metal, plastic, or other materials. The CNC milling process involves using a computer to control the motion of a rotary cutter that removes material from a workpiece. This article will discuss things you need to know about the CNC milling process.
What is CNC milling, and what are its uses?
CNC milling is a machining process that uses computer numerical control (CNC) to cut materials precisely. It can produce complex shapes with high accuracy and repeatability from metal, plastic, or other materials. It is used for many applications, including prototyping, manufacturing parts, making moulds and dies, creating fixtures for production lines, producing 3D sculptures and m ...
The article will cover essential aspects of fluid statics and pressure forces applied to the fluid. The article will start with the absolute pressure gauge and the variation of pressure with depth in different gravitational field manometers and barometers, respectively. Then I will explain the forces that deal with fluids, such as hydrostatic force, buoyant force, etc. So, dear friends, without wasting any time, let’s start.
Pressure
The definition of pressure according to fluid mechanics is as follows:
Pressure is the normal force applied by a fluid per unit area.
Unit of Pressure
The units of pressure Pascal is too small to deal with in practical cases. For instance,
Kilopascal: 1kPa=103Pa
Mega Pascal: 1MPa=106Pa
The three common pressure units used are standard atmosphere ba ...
Hello Friends. I hope you are doing great. Here I am with another exciting topic of fluid mechanics, i.e. flow over bodies. In this article, I will explain the flow of fluids, the flow rate, their nature, the flow in pipes and much more. Fluid mechanics is all related to the fluid and its nature. I will discuss the forces that are on the body that is immersed in a fluid and the flow that is over the body. As the title shows, the main emphasis will be on the lift and drag forces. Moreover, the external and the internal flow will also be discussed in this article. And I am sure that you will enjoy reading this article. So without wasting any time, let us start.
I will start with an introduction to fluid flows.

Hello Friends. I hope you are doing great. In this article, I will cover the nature of flow responsible for the changes in density. The nature of flows responsible for density change is known as compressible flows.
Fluid dynamics and thermodynamics combine for the theory of compressible flows. The compressible flow creates a relationship with the ideal gas. First, I will explain the stagnation state, speed of sound, and then the Mach number. This all comes under compressible flows. Then there come the static and stagnation fluid properties, shock waves, and variation of fluid properties in the case of regular and oblique waves. All of these are discussed in this article. So without wasting any time, let us start with the Stagnation property.

Hello students, I hope this tutorial finds you happy, healthy, and content. The topic we have at hand today is "3D printing", it is a very interesting and versatile topic, and extremely easy to comprehend as well, it would definitely keep you hooked to your screens. You might have heard a lot about 2D and 3D objects, in this digital era almost everyone has at least once heard of it, do you know what is a 3D object?
A 3D object can be defined as,
"An object or structure that has three dimensions which includes width, length, and height."
Definition of 3D Printing
As you are now familiar with the term 3D we shall proceed further with our actual topic, so
Here we have the most commonly asked question of all, what is 3D printing?
